What problem does it solve? Training data goes stale, APIs get deprecated, and best practices evolve, so code written from memory often contains outdated or incorrect framework patterns. This Skill grounds every framework-specific implementation decision in official documentation, so the code you receive is verifiable against authoritative sources rather than guesswork. ## Core Features & Use Cases - Stack Detection: Reads dependency files like package.json, composer.json, requirements.txt, go.mod, Cargo.toml, or Gemfile to identify exact framework and library versions before writing any code. - Documentation-Grounded Implementation: Fetches the specific official documentation page for the feature being implemented, follows documented API signatures, avoids deprecated patterns, and treats fetched content as untrusted data to resist prompt injection. - Source Citation and Conflict Surfacing: Adds full-URL citations in code comments and conversation, quotes relevant passages for non-obvious decisions, and explicitly flags anything that could not be verified. - Use Case: When building a form in a React 19 project, the Skill detects the version from package.json, fetches react.dev documentation for useActionState, implements the modern pattern instead of a deprecated useState approach, and cites the exact doc URL so you can verify the decision. ## Quick Start Ask the agent to implement a framework-specific feature using source-driven development so every pattern is verified against the official docs and cited.
